I'm using OpenJDK11.
I have two Java files in the current folder, that are supposed to run together to be a JavaFX application.
One of them is called Main.java and runs the main window. Another is Alert.java, and is supposed to run an alternate window which is an alert type.
Now, I ran the following command:

javac -cp "c:projectsjavacurrentProject" --module-path "c:Program FilesJavajavafx-sdk-11.0.1lib" --add-modules=javafx.controls,javafx.fxml Alert.java Main.java

While Alert.java compiled just fine, Main.java could not import the Alert class and gave an error on "import Alert". I tried "import Alert.Alert" and "import currentProject.Alert" but still, it didn't work.
Also, I declared package "package currentProject" at the start of each file and it still gave an error.

What am I supposed to do to get it running? I already failed on installing JavaFX on all available IDEs, so I'm not going to use an IDE other than Atom. But how do I compile it properly?

more info -

file structure:

c->projects->java->economicManager->( Alert.java ,Main.java, financialManager.fxml, alert.fxml, Alert.class, Alert$Controller.class, Main.class [previously compiled version])

Alert.java:

package financialManager;



import javafx.stage.Stage;

import javafx.stage.Modality;

import javafx.scene.Scene;

import javafx.scene.Parent;



import javafx.scene.control.Button;

import java.util.Map;



public class Alert {



    public Stage stage;

    private Controler_Class controler;



    public Alert(Parent root) {



        Controler_Class clas = new Controler_Class(root);

        this.controler = clas;



        Scene scene = new Scene(root);

        Stage stage = new Stage();



        stage.initModality(Modality.APPLICATION_MODAL);

        stage.setTitle("financial report");

        stage.setScene(scene);



        this.stage = stage;

        stage.showAndWait();

    }



    private class Controler_Class{



        Parent root;



        public Controler_Class(Parent root){



        }

    }

}

Main.java:

package financialManager;



import Alert;



import javafx.application.Application;

import javafx.stage.Stage;

import javafx.fxml.FXMLLoader;

import javafx.scene.Scene;

import javafx.scene.Parent;



import javafx.scene.control.ListView;

import javafx.scene.control.SplitPane;

import javafx.scene.control.Button;

import javafx.scene.layout.AnchorPane;

import javafx.scene.layout.VBox;



import java.util.Map;



public class Main extends Application{



    @Override

    public void start(Stage stage) throws Exception{



        final int width = 300;

        final int height = 450;



        stage.setTitle("hello mofos");



        FXMLLoader loader = new FXMLLoader(getClass().getResource("financialManager.fxml"));



        Parent root = loader.load();

        Scene scene = new Scene(root, width, height);



        Map<String, Object> mapper = loader.getNamespace();

        AnchorPane pane = (AnchorPane) mapper.get("splitpane1_anchorpane");



        if(pane != null)

            SplitPane.setResizableWithParent(pane, false);

        else

            System.out.println("it's null you idiot!");



        Button btn = (Button) mapper.get("economicReport");



        btn.setOnMouseClicked((event) -> {



            FXMLLoader loader2 = new FXMLLoader(getClass().getResource("alert.fxml"));

            Parent parent = loader2.load();

            Alert alert = new Alert(parent);

        });



        /*

        ChangeListener<Number> stageSizeListener = (observable, oldValue, newValue) ->

                pane.setDividerPositions(0.20219435736677116);



        stage.widthProperty().addListener(stageSizeListener);

        stage.heightProperty().addListener(stageSizeListener);

        */



        stage.setScene(scene);

        stage.show();

    }



    public static void main(String args){



        launch();

    }

}

I see that you are importing the Alert class wrongly. Your package is financialManager, so you should use it in the import line like this:

import financialManager.Alert;

About your issues with IDEs, I made JavaFX work fine with Eclipse and IntelliJ on OpenJDK 11 without any issues a few days ago - For OpenJDK you will need OpenJFX, and if you are interesting in some reading, this is the link from Oracle's blog on their plans for JavaFX.

Good luck!
